Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Abstract Detachable pressure sensitive adhesives (PSAs) show great potential in recycling the bonded components toward a circular economy, yet existing challenges such as strict conditions, and time‐consuming, adhesive residues after detachment significantly hinder developments applications. Here, ionoadhesive (PSIA) tape is first designed that has excellent interfacial toughness to various substrates (≈1.8 kJ m −2 ) can be electrically detached with high efficiency under safe voltages (≥90% within 1 min). The unique properties are achieved by introducing liquid‐free lithium salt into poly(ionic liquids) establish multiple non‐covalent interactions (NCIs) including strong electrostatic interactions, moderate bonds, weak ion‐dipole hydrogen bonding interactions. NCIs not only strengthen physical crosslinking networks improve mechanical performances but promote dissociation of ion transport properties. Additionally, elaborately low T g intrinsic modulus features endow PSIA adhesion reworkability, recyclability, re‐adhesion ability. It believed this work offers new strategy for designing detachable fully recyclable tapes, which facilitates reuse reduces industrial waste.
